- Description: Black Economic Empowerment is an ideology and policy that was effected so as to streamline the inequalities that were and have been left to stand after the apartheid era in South Africa. Despite the mixed reactions that would surface as a result of the underpinnings of the policy, the main focus of the policy was and still is to provide for equality and build better business among the economic minority who in this case are the “black” people of South Africa. This report focuses on the policy and the different guidelines that have been set in place to counter the inequalities in businesses and economy with focus being on SMMEs and looking at ways in which various sections, especially the score card, with regard to exemptions to small businesses, how this aids them in achieving BEE compliance. The research accomplished this by looking at the requirements of the score card, focusing mainly on the stipulations placed on SMMEs and by the use of literary reports gathered information that would show whether the exemptions give the said enterprises added competitive advantage. The research produced a couple of findings; that although theoretically the necessity of boosting economic growth and business of one of the most productive enterprise sectors in an economy and the fact that the score card has focused infinitely on the need for SMMEs not to be fully focused on a specific cluster of criterion in the score card but more on which criterion would work best for them and which ones are easy to maneuver around to ensure maximum growth and contribution, there is the loop hole that is experienced of how this criterion is met and passed with disregard to actualization of the need to adhere to the strictness of the rules of how compliance is attained. There was also the main issue of fronting which is the falsification of ownership of a company by providing misleading information about the directors and owners of the business. The main conclusions drawn from this research are that it is important not to lose the foresight that the policy is meant to enhance and grow the economic ability of a sector and build business through which the policy makes very heavy recommendations but there are shortfalls experienced with regard to how compliance is approached putting into consideration that SMMEs have been given exemptions in the number of pillars of the score card they can apply to their business. It is also important to note that the influence and bulldozing that is expected when it comes to dealing with policies of this nature is not to be sidelined. This research aims to look at the discrepancies that are set out within the structures that hold the policy together so as to attain maximum results.

- Description: Although performers have been rife for centuries, no legal regime was required for their protection owing to the fact that the nature of their performances was transitory. It was not until the invention of the phonogram in 1877, that the need to provide performers with the means to protect the unauthorised uses of their performances became an issue. The subsequent development of performers' rights has been fuelled by the rapid technological developments of the modern age which has prompted the international community to respond through various international instruments. Performers initially sought protection in terms of the Berne Convention in 1886, but it was not until the Rome Convention in 1961 that performers were first accorded international recognition. This was followed by the TRIPs Agreement in 1994 and the WPPT in 1996. This work involves an investigation into the historical development of performers' rights in the United Kingdom and South Africa. This is followed by a comparative analysis of the current state of performers' rights as between the United Kingdom and South Africa with a view to proposing recommendations for improving the level of protection accorded performers in South Africa. Arguments in favour of a regime of performers' rights as well as possible counter-arguments have been advanced. The general development of performers' rights as a related or neighbouring right to copyright is focussed on. The development of performers' rights in the United Kingdom is discussed with reference to the first English legislative form of protection, namely the Dramatic and Musical Performers' Protection Act, 1925. This Act only provided performers with criminal remedies, a view that prevailed through several subsequent enactments designed to protect performers as a result of ratification of the Rome Convention. It was not until 1988 when the decision in Rickless v United Artists Corp prompted the legislature to grant performers with enforceable civil remedies through the enactment of the Copyright, Designs and Patents Act, 1988. Several European Union Council Directives aimed at harmonising the law relating to performers' rights throughout the Union were issued, mainly in response to the TRIPS Agreement. In order to comply with these Directives, the United Kingdom passed Regulations to bring about the necessary amendments to the Copyright, Designs and Patents Act. Performers in the United Kingdom were granted moral rights in 2006 as a result of the United Kingdom's ratification of the WPPT. The development of performers' rights in South Africa has been slow when compared to that of the United Kingdom. It was not until 1967 that performers were first legally recognised in South Africa. Although South Africa has yet to ratify the Rome Convention, it was stated in South African Broadcasting Corporation v Pollecutt that the Act was clearly passed with a view to complying with the Convention. South Africa's ratification of the TRIPs Agreement brought about amendments to the Act, particularly regarding the duration of protection which was increased from 20 to 50 years. Although South Africa played an active role in the conclusion of the WPPT, it has yet to ratify it. However, amendments were made to the Act in line with this Treaty, such as the incorporation of “expressions of folklore” within the ambit of protection, and the granting of a right to receive royalties whenever a performer's performances are broadcast. This is commonly known as needletime. South Africa's reluctance to grant performers with moral rights as provided for by the Treaty is noteworthy. The introduction of needletime into South African law has resulted in a fierce debate between collecting societies (who represent authors and performers) and the NAB (who represent users of performances). Mainly as a result of this dispute, performers in South Africa have, to date, not received any royalties due to them. The protection of traditional knowledge has also received attention of late with the Intellectual Property Laws Amendment Bill, 2010 which aims to bring traditional knowledge inter alia within the ambit of the Performers' Protection Act. The current state of performers' rights in the United Kingdom and South Africa are compared in order to identify ways in which the level of protection accorded performers in South Africa could be improved. The Copyright, Designs and Patents Act is compared with the Performers' Protection Act through emphasis being placed on the definition of a “performer”; the definition of a “performance”; the nature of performers' rights; exceptions to infringement; the term of protection; the retrospectivity of the legislation; and the enforcement measures in place. Upon analysis, it was found that the Performers' Protection Act can be amended in several ways in order to increase the level of protection accorded performers in South Africa.

- Description: The purpose of this article was to investigate the feasibility of incorporating didanosine (DDI) into nanostructured lipid carriers (NLC) for potential treatment of AIDS dementia complex. Aqueous DDI-free and DDI-loaded NLC were manufactured using hot high-pressure homogenization. The lipid matrix contained a mixture of Precirol ® ATO 5 and Transcutol ® HP. Photon correlation spectroscopy revealed that the mean particle size for all formulations was below 250 nm with narrow polydispersity indices. In addition, the d99% values for all formulations determined using laser diffractometry were below 400 nm with the span values ranging from 0.84 to 1.0. The zeta potential values ranged from −18.4 to −11.4 mV and the encapsulation efficiency of NLC for DDI ranged from 33.02% to 78.34%. These parameters remained relatively constant for all formulations tested following storage for 2 months at 25°C indicating that all the formulations were relatively stable. Differential scanning calorimetry revealed a decrease in the degree of crystallinity of NLC in all formulations developed relative to the bulk lipid material. In addition, wide-angle X-ray scattering showed that NLC in all formulations tested existed in a single β-modification form and that DDI that had been incorporated into the NLC appeared to be molecularly dispersed in the lipid matrices. Images of the NLC formulations obtained using transmission electron microscopy revealed that all formulations contained a mixture of spherical and nonspherical particles irrespective of the amount of DDI that was added during the manufacture of the formulations.

- Description: Tourism has social and economic benefits. Economic benefits are received through tourists visiting tourist attractions. Social benefits related to benefits tourists receive personally when visiting tourist attractions. The number of individuals that are obese are constantly increasing and leads to hazardous medical conditions. The aim of this research study was to determine the extent to which geocaching can be used to increase tourism and decrease obesity. Geocaching is similar to a treasure hunt where participant use clues and a Global Positioning System device to find a treasure that are called a cache. The cache is filled with trinkets that are exchanged by participants that find the cache. Students of the second avenue campus of the Nelson Mandela Metropolitan University were used as respondents and given information on what geocaching involve. Three geocaches were hidden in The Boardwalk Casino and Entertainment World in Summerstrand, Port Elizabeth. The respondents met at The Boardwalk Casino and Entertainment World where a clue and map was provided. After finding the cache the respondents was asked to complete an anonymous questionnaire. The results were calculated and conclusions and recommendations were made. The primary research process was conducted over too short a period of time to conclude whether it can lead to a reduction in obesity. However geocaching experience by respondents did show that the process of geocaching involves physical exercise, which is needed for losing weight. Research also indicated that respondents would like to geocache with family and friends. Geocaching with family and friends involves support which secondary research have also proven is important to losing weight and decreasing obesity. Respondents indicated that they enjoyed geocaching and would like to geocache in their free time. The indication of enjoying geocaching, participating in geocaching during free time allows travelling for leisure purposes as to geocache travelling is necessary and the majority of geocaches is hidden at tourist attractions. The combination of travelling to tourist attractions, enjoying the experience and partaking in physical exercise with family and friends involve two of the three main aspects seen as helping to reduce obesity: enjoyable physical activity and support from family and friends. The conclusion is therefore that geocaching can be utilised to increase tourism and reduce obesity.

- Description: The commercialization of hospitality established arguably the oldest profession. Historically small commercial hospitality establishments, known as inns in the western world, were of ill repute. Perhaps connected to their reputation, this category of accommodation facility has been seriously neglected as an area of academic inquiry, particularly from the perspective of the host. While there has been a huge growth in the interdisciplinary field of tourism studies in recent decades, little attention has been paid to the role of the host in the host-guest relationship at whatever level of analysis. This thesis seeks to redress the balance. Hospitality is a basic form of social bonding. This type of bonding, where a hierarchy between strangers is implicit (as with hosts and guests), may be termed ‘nexilitas’; nexilitas is a form of social bonding in liminal circumstances. To that extent it is comparable to ‘communitas’ which describes social bonding between equals in certain liminal circumstances. The difference is that nexilitas is a form of bonding between individuals in a complex power relationship. The host controls the hospitality space, but custom also empowers the guest with certain expectations, especially in the commercial context. The thesis identifies the various forms of hospitality – traditional ‘true’ or ‘pure’ hospitality, social hospitality, cultural hospitality and commercial hospitality – and discusses these critically in their historical and cross-cultural contexts, with emphasis on the perspective of the host. The passage of hospitality is then traced through the three phases of preliminality, liminality and post-liminality and discussed along the themes anticipation, arrival and accommodation and finally departure of the guest. While the historical and ethnographic review is mainly based on written histories and the experiences of other anthropologists as guests as well as ethnographers, the passage of hospitality draws on the multi-sited auto-anthropological experiences of the author, both as host and as ethnographer of contemporary South African hosts in small owner-managed commercial hospitality establishments.

Evaluation of model systems for the study of protein association / incorporation of Beta-Methylamino-L-Alanine (BMAA)

- Description: β-methylamino-L-alanine (BMAA) is thought to be a contributing factor of Amyotrophic Lateral Sclerosis-Parkinsonism Dementia Complex (ALS/PDC). It has been shown that the levels of toxin ingestion by humans are too low to cause disease. However, it has recently been theorized that this toxin is bioaccumulated within cells. Via a process of slow release from this reservoir, the BMAA is able to bring about neurotoxicity. Mechanisms of uptake and bioaccumulation of BMAA have been proposed in several publications; however the mechanism of protein incorporation of BMAA has not yet been identified. Identifying suitable model systems would be a prerequisite in order for future studies on BMAA protein incorporation. Three specific models were therefore chosen for investigation; mammalian cell lines including C2C12 and HT29, a prokaryotic (E. coli) expression system and yeast cells. The cytotoxity of BMAA was established for the mammalian cell lines and further investigation of BMAA incorporation into cellular proteins was performed on all three above mentioned models. Samples were run on HPLC-MS in order to determine uptake of BMAA into cells or lack thereof. Results indicate negligible cytotoxicity as measured by MTT and CellTitre Blue assays, limited uptake and protein incorporation of BMAA within the prokaryotic model and insignificant uptake of BMAA by yeast cells. Although the uptake of BMAA in the prokaryotic model was not extensive, there was indeed uptake. BMAA was not only taken up into the cells but was also observed in inclusion body protein samples after hydrolysis. After further investigation and use, this model could very well provide researchers with information pertaining to the mechanism of association of BMAA with proteins. Although the other models provided negative results, this research was valuable in the sense that one can narrow down the number of possible model systems available. Also, in seeking models for studying protein association/incorporation, the use of the final target cell is not relevant or necessary as the purpose of the research was to identify a model system in which the mechanism of protein association/incorporation can, in future, be studied.

- Description: A rich literature exists on local democracy and participation in South Africa. While the importance of participation is routinely built into the rhetoric of government, debate has increasingly focused on the dysfunctionality of participatory mechanisms and institutions in post-apartheid South Africa.

- Description: A rich literature exists on local democracy and participation in South Africa. While the importance of participation is routinely built into the rhetoric of government, debate has increasingly focused on the dysfunctionality of participatory mechanisms and institutions in post-apartheid South Africa. Processes aimed ostensibly at empowering citizens, act in practice as instruments of social control, disempowerment and cooptation. The present article contributes to these debates by way of a critique of the approach used by the South African state, in partnership with the non-governmental sector, in what are called abortion ‘values clarification’ (VC) workshops.

Shaking a hornets' nest: pitfalls of abortion counselling in a secular constitutional order–a view from South Africa

- Description: There exists an enormous gulf between the aspirations of South Africa's abortion legislation – among the most liberal in the world – and its implementation. One weakness in the provision of abortion services in South Africa is the absence of comprehensive abortion counselling services. On the face of it, the idea that counselling ought, as a matter of course, to be a significant component of a country's termination of pregnancy service provision, seems both straightforwardly sensible and politically innocent. This paper describes how abortion counselling has historically, in many different contexts, been saturated with questionable assumptions about women and their bodies. Counselling has more often than not been deployed, either as the formal policy of states or through informal mechanisms, as a means of curbing the right to abortion rather than deepening the meaning of that right. Differing approaches to counselling emerge as a reflection of contestations over reproductive and gender politics. Specifying an appropriate model for the provision of state-sponsored abortion counselling in the public health sector of a secular constitutional state provokes more of a hornet's nest of dilemmas than is sometimes supposed.

- Description: The Recognition of Customary Marriages Act (RCMA) 1998, recognises customary marriages which are “negotiated, celebrated or concluded according to any of the systems of indigenous African customary law which exist in South Africa” including polygamous marriages. The Act arises in the context of South Africa's Constitution which bans discrimination on grounds of culture and sexual orientation and allows for heterogeneity in its definitions of marriage and the family. A pluralist approach to family jurisprudence, however, is sometimes conceived of as setting up an irresolvable tension between the constitutional commitment to gender equality and protection for patriarchal prerogatives sanctioned by customary law. The fact that rights sometimes collide with one another is one of the reasons why it is impossible always to treat rights as absolute. When rights clash the question that arises is which of the rights that find themselves in tension with one another should give way and why?

- Description: Recent ructions in South Africa's ruling African National Congress have been described from time to time in the media as signalling a dangerous shift towards ‘populism’. The article examines this contention. It argues that South Africa is witnessing a significant challenge to the founding precepts of constitutional democracy. This challenge emanates from the (populist) equation of democracy with ‘the will of the people’. The article unpacks some of the implications of reducing democracy to majoritarianism. It provides also an analysis of why populist appeals of various kinds have been so appealing to South African voters 15 years into democracy. The article argues that the challenges that are currently being experienced in relation to democratisation in South Africa have to do with the inherent tension between the animating ideology of democracy, which suggests that power resides with the people, and the practical functioning of democracy, which relies on the devolution of power to the representatives chosen by a section of the people who rely on order and predictability in the polity in order to govern in a workable way. Populist appeals, it is argued, exploit this tension. But what makes it possible for this strategy to succeed is the failure on the part of political elites to engage in the process of building democracy by way of inculcating respect for democratic values.

- Description: South Africa’s economy is in a phase of transformation. As part of this process, the South African government has identified the development of economic activities amongst previously disadvantaged black communities. However, this noble intent is challenged by a lack of entrepreneurial skills, which are seen as important elements in the economic development effort and necessary to achieve transformation goals and objectives (Smith, 2004). Since the apartheid era, South Africa has seen the emergence of two distinct economic sectors: a first world economy, consisting mostly of white owned and formal businesses, and a third world economy, consisting of mostly black owned and informal businesses. Economic activities of emerging entrepreneurs have been restricted to mostly the black townships and rural areas, whereas first world entrepreneurs have been actively involved in mainstream economic activities. The separation of emerging and first world entrepreneurs has resulted in a wide gap in entrepreneurial and technical skills and knowledge between the two. This imbalance has maintained a situation in which the minority of the population controls more than 80 per cent of the wealth of the country. Upon gaining independence in 1994, the new South African government embarked on the Reconstruction and Development Programme (RDP) to redress the imbalances of the past (GEM, 2001; GEM, 2002). The government has since also adopted the Growth Employment and Redistribution (GEAR) macroeconomic strategy to grow the economy, create employment and redistribute wealth. To accelerate the implementation of GEAR, the government has passed a number of Acts, namely: The National Small Business Promotion Act (102/1996), Skills Development Act (97/1998), Affirmative Procurement Act (5/2000), Mineral and Petroleum Resources Act (28/2002) and, most recently, the Mining Charter (2003), Petroleum Charter (2003), Financial services Charter (2003), and the Information Communications Technology (ICT) Charter (2004). Small business has been seen by government as a vehicle to create employment, promote economic growth and redistribute wealth; as such the promotion of entrepreneurship has been identified as a critical aspect of GEAR. However, despite supportive legislation and programmes, South Africa’s entrepreneurship rating remains below average, as evidenced by the findings of the Global Entrepreneurial Monitor reports (GEM, 2001; GEM, 2002). The wide gap in skills and knowledge between emerging and first world entrepreneurs in South Africa is a contributing factor to the country’s poor rating – and it is expected to widen as the new knowledge economy unfolds, if corrective measures are not taken by the government or private sector.

- Description: Research suggests that there is a relationship between religion and business ethics. When looking at the South African society and the statistics that says that 80 percent of the population is Christian but on the other hand we are confronted within this country with increasing incidents of corruption in private companies as well as in public services. Why would that be the case? This study seeks to understand if Christianity or the local church really makes an impact on the lives of its members. The research starts of by looking at behaviour in general and what constitute to good ethical decision-making. In the study on Christian ethics it becomes clear that there is a strong appeal in the Bible on ethical behaviour. The Bible goes as far as to claim that, when in a relationship with the Lord, the followers will show His character in the way they live at home and the way they behave and make ethical decisions at the workplace. This study used focus groups to research the role of the local church in changing behaviour. The study finds that Christianity per se does not change the behaviour of church members. The church members‘ definition of the church largely determines the impact the church will have on their lives. In the study on the Christian ethics it was clear that ethics were seen as something that was formed in communities and not by rules or regulations. It was not a case of people telling others what to do and what not. It was more a case of mentors that helped others to live differently in community with others. The study finds that when the local church is build on relationships and if there is a strong sense of community, the church has a huge impact on the lives of its members. This suggests that the local church should be more focused on strong and intimate relationships and not so much on the church as organisation or institute. This is also important for the businesses that will employ these members because they will make better ethical decisions.

- Description: While the growing literature on South Africa’s healthcare and epidemics has often mentioned cholera in passing, there is as yet little academic work dedicated to it. This thesis addresses that deficit by examining the causes, spread and extent of cholera in South Africa between 1980 and 2003. Furthermore, it examines cholerarelated coverage in two newspapers, the Daily Dispatch and the Eastern Province Herald to determine how cholera and people with cholera were represented, and show how changes in the coverage of two major epidemics between 1980 and 2003 exemplify the political transition in South Africa, reflect changing political ideologies and reveal the shifting role of media within this period. The thesis argues three main points. Firstly, that representations of cholera and those who were sick with cholera were based on long-standing tropes connecting disease, class and ‘race’. Secondly, that policy-making based on these tropes influenced the unfair distribution and quality of health resources along racial lines, resulting in cholera outbreaks during the apartheid era. Failure to address these inequities post-apartheid, and the replacement of racial bias with discrimination on the grounds of socioeconomic development, resulted in further cholera outbreaks. Thirdly, using Alan Bell’s newspaper-discourse analysis framework to examine cholera-related articles the thesis compares and contrasts apartheid and postapartheid coverage in the two newspapers. This analysis reveals that during the 1980s the coverage was uncritical of the government’s handling of the epidemic or of its racially-discriminatory healthcare system. The newspapers uncritically accepted government-employed medical professionals as the final authorities on the epidemic, excluding alternative viewpoints. The coverage also “blamed the victim”, constructing affected “black” groups as potential threats to healthy “white” communities. Conversely, post–1994 coverage was criticised the government’s handling of the epidemic and the state of the public healthcare system. Government-employed medical professionals or spokespeople were not accepted as incontestable authorities and a range of sources were included. The coverage also shifted blame for the outbreaks to the government and its failure to address public health service delivery and rural development problems. The thesis shows the historical threat to the health of communities posed by uncaring governments.

The use of a Roving Creel Survey to monitor exploited coastal fish species in the Goukamma Marine Ptrotected Area, South Africa

- Description: A fishery-dependant monitoring method of the recreational shore-based fishery was undertaken in the Goukamma Marine Protected Area (MPA) on the south coast of South Africa for a period of 17 months. The method used was a roving creel survey (RCS), with dates, times and starting locations chosen by stratified random sampling. The MPA was divided into two sections, Buffalo Bay and Groenvlei, and all anglers encountered were interviewed. Catch and effort data were collected and catch per unit effort (CPUE) was calculated from this. The spatial distribution of anglers was also mapped. A generalized linear model (GLM) was fitted to the effort data to determine the effects of month and day type on the variability of effort in each section. Fitted values showed that effort was significantly higher on weekends than on week days, in both sections. A total average of 3662 anglers fishing 21 428 hours annually is estimated within the reserve with a mean trip length of 5.85 hours. Angler numbers were higher per unit coastline length in Buffalo Bay than Groenvlei, but fishing effort (angler hours) was higher in Groenvlei. Density distributions showed that anglers were clumped in easily accessible areas and that they favored rocky areas and mixed shores over sandy shores. Catch documented between October 2008 and December 2009 included a total of 361 fish, of 27 species from 12 families. Sparidae had the highest contribution (12 species). A Shannon-Weiner diversity index showed that diversity was higher in Buffalo Bay (0.81) than Groenvlei (0.57). Catch composition of retained fish (336 individuals) showed that the six numerically most important species were blacktail (Diplodus sargus capensis) (66 percent of catch), followed by galjoen (Dichistius capensis) at 11 percent, Cape stumpnose (Rhabdosargus holubi), belman (Umbrina robinsonii) and strepie at 3 percent, and elf (Pomatomus saltatrix) at 2 percent. Catch composition of an earlier study in Goukamma (Pradervand and Hiseman 2006) was compared with the present study, as well as data from the De Hoop MPA, which is closed to fishing. A multi-dimensional scaling plot of catch composition showed tight clustering of the De Hoop samples, and high variability among the Goukamma samples. A bray-curtis similarity index and dendrogram of similarity between study sites and study periods showed that there was an 83 percent similarity among De Hoop samples and a 75 percent similarity among Goukamma samples (ignoring the two outliers). The two sites are different with respect to species composition, but this is expected because they are different areas. Differences between time periods in Goukamma (i.e. the previous study versus the present study) were not significant. The most significant result from the catch composition analyses is the high variability among the Goukamma samples. This can be explained by the variable fishing methods used by anglers in Goukamma, compared with the standardized fishing methods used by researchers in De Hoop, and the fact that fish are more abundant and populations are more stable in De Hoop – giving higher sample sizes which reduce the variability in the statistics. Species-specific CPUE was calculated for the six numerically most important species. In both sections, CPUE was highest for blacktail, with an average of 0.133 fish per hour for Groenvlei, and 0.060 fish per hour for Buffalo Bay, over the 12 months. The second highest CPUE values per section were 0.030 for galjoen in Groenvlei and 0.039 for strepie in Buffalo Bay. Remaining CPUE values ranged from 0.014 (belman in Groenvlei) to the lowest value of 0.001 (strepie in Groenvlei). Total estimated CPUE for these six species in the MPA using the estimated effort and catch results amounted to 0.018 fish per hour. An annual estimated 3897 fish were landed in the reserve during 2009. Most fish (n=2481, 64 percent) were caught in the Groenvlei section. Numbers of blacktail were the highest of all species, within both sections (2353 fish). Strepie was the next most common (561 fish), but was caught almost entirely within the Buffalo Bay section (97 percent of individuals), followed by galjoen (548 fish) caught mostly within the Groenvlei section (92 percent of individuals). Size comparisons of the six species between the Goukamma and De Hoop MPAs showed that ranges in size are similar, but there are substantial differences in mean sizes between the two MPAs. Sample sizes of all species from the Goukamma MPA were too small to draw conclusions about stock status, except for blacktail. The Goukamma MPA is a popular fishing destination and angler effort is high. It can be considered a node of exploitation for surf zone fish, for which it provides no protection. Even though the MPA allows shore angling, sustainable fishing practices should be incorporated in management plans if the MPA is expected to protect and conserve its stocks. Of noteworthy concern is the occurrence of illegal night fishing (the public may not enter the reserve between sunrise and sunset) which leads to underestimates of catch and effort (night surveys were not conducted because of safety concerns). It is recommended that more communication should take place between the angling community and the reserve management. Sign boards giving information on species which are under pressure, and why they are under pressure, with a short explanation on their life cycles, is advised. The roving creel survey method was suitable for the study area and delivered statistically rigorous results. I thus recommend that it is continued in the future by management. I make some recommendations for reducing costs of future surveys, as well as for altering the survey design if funds are very limited.

Angler numbers were higher per unit coastline length in Buffalo Bay than Groenvlei, but fishing effort (angler hours) was higher in Groenvlei. Density distributions showed that anglers were clumped in easily accessible areas and that they favored rocky areas and mixed shores over sandy shores. Catch documented between October 2008 and December 2009 included a total of 361 fish, of 27 species from 12 families. Sparidae had the highest contribution (12 species). A Shannon-Weiner diversity index showed that diversity was higher in Buffalo Bay (0.81) than Groenvlei (0.57). Catch composition of retained fish (336 individuals) showed that the six numerically most important species were blacktail (Diplodus sargus capensis) (66 percent of catch), followed by galjoen (Dichistius capensis) at 11 percent, Cape stumpnose (Rhabdosargus holubi), belman (Umbrina robinsonii) and strepie at 3 percent, and elf (Pomatomus saltatrix) at 2 percent. Catch composition of an earlier study in Goukamma (Pradervand and Hiseman 2006) was compared with the present study, as well as data from the De Hoop MPA, which is closed to fishing. A multi-dimensional scaling plot of catch composition showed tight clustering of the De Hoop samples, and high variability among the Goukamma samples. A bray-curtis similarity index and dendrogram of similarity between study sites and study periods showed that there was an 83 percent similarity among De Hoop samples and a 75 percent similarity among Goukamma samples (ignoring the two outliers). The two sites are different with respect to species composition, but this is expected because they are different areas. Differences between time periods in Goukamma (i.e. the previous study versus the present study) were not significant. The most significant result from the catch composition analyses is the high variability among the Goukamma samples. This can be explained by the variable fishing methods used by anglers in Goukamma, compared with the standardized fishing methods used by researchers in De Hoop, and the fact that fish are more abundant and populations are more stable in De Hoop – giving higher sample sizes which reduce the variability in the statistics. Species-specific CPUE was calculated for the six numerically most important species. In both sections, CPUE was highest for blacktail, with an average of 0.133 fish per hour for Groenvlei, and 0.060 fish per hour for Buffalo Bay, over the 12 months. The second highest CPUE values per section were 0.030 for galjoen in Groenvlei and 0.039 for strepie in Buffalo Bay. Remaining CPUE values ranged from 0.014 (belman in Groenvlei) to the lowest value of 0.001 (strepie in Groenvlei). Total estimated CPUE for these six species in the MPA using the estimated effort and catch results amounted to 0.018 fish per hour. An annual estimated 3897 fish were landed in the reserve during 2009. Most fish (n=2481, 64 percent) were caught in the Groenvlei section. Numbers of blacktail were the highest of all species, within both sections (2353 fish). Strepie was the next most common (561 fish), but was caught almost entirely within the Buffalo Bay section (97 percent of individuals), followed by galjoen (548 fish) caught mostly within the Groenvlei section (92 percent of individuals). Size comparisons of the six species between the Goukamma and De Hoop MPAs showed that ranges in size are similar, but there are substantial differences in mean sizes between the two MPAs. Sample sizes of all species from the Goukamma MPA were too small to draw conclusions about stock status, except for blacktail. The Goukamma MPA is a popular fishing destination and angler effort is high. It can be considered a node of exploitation for surf zone fish, for which it provides no protection. Even though the MPA allows shore angling, sustainable fishing practices should be incorporated in management plans if the MPA is expected to protect and conserve its stocks. Of noteworthy concern is the occurrence of illegal night fishing (the public may not enter the reserve between sunrise and sunset) which leads to underestimates of catch and effort (night surveys were not conducted because of safety concerns). It is recommended that more communication should take place between the angling community and the reserve management. Sign boards giving information on species which are under pressure, and why they are under pressure, with a short explanation on their life cycles, is advised. The roving creel survey method was suitable for the study area and delivered statistically rigorous results. I thus recommend that it is continued in the future by management. I make some recommendations for reducing costs of future surveys, as well as for altering the survey design if funds are very limited.

- Description: The main purpose of this study was to evaluate the motivational levels of employees at CompSol, a contemporary South African organisation. Research for the study included a literature study of both the content and process theories of motivation in order to identify those factors that are important to consider when evaluating the levels of employee motivation. An empirical study was conducted after the appropriate measuring instrument was developed. The purpose of the measuring instrument was to identify the rank importance of these identified factors of motivation and to evaluate the levels of employee motivation by measuring the extent to which these factors are provided for in the organisation. A sample was selected from the target population, via cluster sampling, from the largest functional department within the organisation, namely the Claims processing department. The group’s dominant locus of control was also measured through the use of an appropriate measuring instrument. The major findings indicated that some of the factors of motivation were provided for to a great extent, while others had serious shortcomings. The findings were grouped into the different job title categories of the respondents in order to compare the overall responses of the groups, aimed at identifying trends, commonalities and differences. Findings also indicated that the majority of the participants have an external locus of control. The researcher suggested certain recommendations for those areas where findings indicated shortcomings, in an attempt to increase the overall levels of motivation within this specific functional department in the organisation.

- Description: Globalisation and the falling of trade barriers across the world have changed the way organisations conduct their business. Organisations have to become more competitive to compete against local rivals and imported products. Employees fulfil a vital role in this strategy and productive employees can enable organisations to accomplish this goal. Employees need to be motivated to contribute to the challenges of globalisation and ultimately the success of the organisation. Organisations therefore need to create a motivating climate wherein employees can perform. A number of motivational theories are recorded, but older theories make the assumption than an average human being exists. The more modern theories, which identify the relationship between dynamic variables, are more relevant but to a large extent do not consider the influence of trade unions. Trade unions are still very active in South Africa, and a combined effort by organisations and trade unions could result in a win-win outcome for both parties. Rewards and recognition drive behaviour which will result in enhanced productivity. Monetary rewards are the preferred incentive amongst employees, but the effect of training and development opportunities are often underestimated and under-utilised. Employees are generally eager to improve their skills levels, which could have a positive medium to long term impact on the organisation. Effective leadership is crucial to improved productivity and leaders have to create the environment for employees to perform. Traditional management styles are no longer effective and modern leaders have to develop their skills to achieve sustainability of the organisation.

- Description: Complaints of crop damage by cranes on planted maize in the North Eastern Cape, South Africa, have been increasing since the mid-1990‘s, and in some instances severe losses have been reported. Crop damage by the Grey Crowned Crane Balearica regulorum regulorum near the town of Maclear (31º04´S 28º22´E), has been quantified over two growing seasons, and assessed relative to losses caused by foraging Cape Crows Corvus capensis and other feeding damage assumed to be caused by insects. Twelve fields were selected based on previous patterns of crop depredation. Maize seed in seven of the fields was treated with the chemical ‗Gaucho‘ and five fields were planted with untreated maize. In order to determine the source of losses, twenty quadrats (4 m x 4 m) randomly distributed within each field were visited on average every second day, for a period of up to twenty eight days. Results indicate that seed treatments do act as a deterrent to feeding by both cranes and crows, however crane damage is generally insignificant compared to other sources of damage. My study also reviewed past sightings data of the Grey Crowned Crane in an effort to determine if the conversion of former grassland to plantations in this region may have increased foraging activity in maize fields. The data did not allow for clear-cut conclusions regarding changes in distribution or population trends. Conclusions provide direct input into the management of agricultural areas by enabling landowners to take steps to mitigate crop damage. These mitigation measures may either involve the application of seed treatments, or the planting of low risk crops in high risk areas. Future studies should consider the ppossible detrimental effects of chemical seed treatments on crane biology.

- Description: The purpose of the research was to improve the use of electronic human resource management in South African businesses by investigating that there is a positive impact when implementing e-HRM on the human resource management function. The research was carried out within a South African business, whose parent business concern is based overseas and has branches operating within South Africa The research was significant as it shaped the researcher’s concern as to whether electronic human resource would be beneficial to a South African business if the business superiors decide to implement e-HRM within their business opinion and what impact it would have. The methodological components that guided the research were a structured questionnaire that was distributed by using a combination of convenience, snowball, and judgemental sampling techniques. Certain aspects highlighted in the literature review were used as the framework for the development of a questionnaire to assess how people perceive the implementation of e-HR on their working environment and if e-HR has helped the business run more efficiently and effectively. Six hypotheses were tested and all were accepted. The potential for generalisations of the findings are that given the potential that e-HRM has for the transformation of human resource, it is reasonable to expect that the sizeable changes required, both in organisation and mindset, are likely to provoke resistance from various end users. What was learned was that HR is often hindered by a multitude of manual, paper based processes and transactions, such as tax, payroll and benefits information, that are costly, prone to errors and time-consuming to manage. This makes it difficult for HR organisations to focus on higher value business in initiatives that may help to drive the profitability and efficiency of the organisations. The implication of the findings about the impact of the implementation of e-HR on the Human Resource Management function was that firms need to figure out how to make technology feasible and industrious, as managers and Human Resource professionals are responsible for redefining how work at their firms or business flow as they need to keep ahead of the information curve and therefore learn how to influence information for business results to be more efficient and effective. The theoretical and practical implications of the findings are discussed and recommendations based on these findings are provided.

- Description: Although it is generally acknowledged that critical career-related concepts and attitudes are first formed in childhood, research has focused little attention on this developmental stage. Statements about children‘s career development as an integral dimension of human development date to the early 1950s, yet limited research has investigated this interrelationship. It is imperative to gain a greater understanding of childhood career development in order to better prepare children for their future. The overall purpose of this study is to explore the interrelationship of childhood development and childhood career development. An exploratory-descriptive quantitative research method was used. Thirty participants (all eight year-old girls from a middle class, English speaking background) were selected through non-probability purposive sampling. Data were gathered from the Griffiths Mental Development Scales – Extended Revised (GMDS-ER) and the Childhood Career Development Scale (CCDS) and analysed using descriptive and inferential statistics. The results indicated a correlation, although not statistically significant, between childhood development and childhood career development, thus indicating a weak positive correlation between the two variables. Statistically significant relationships were established between certain subscales of the GMDS-ER and CCDS, namely Language and Exploration, Eye-Hand Co-ordination and Key Figures, and Practical Reasoning and Planning. The results from this study, although not conclusive, are groundbreaking in this neglected area of research as they indicate an interrelationship between childhood development and childhood career development. This research is an initial step in investigating this interrelationship and it is the hope of the researcher that it will stimulate further research in this area.

- Description: I investigated the return of plant canopy diversity to degraded spekboom thicket landscapes under restoration treatment. I attempted the reintroduction of five nursery propagated and naturally-occurring plant species in severely degraded Portulacaria afra Jacq. (spekboom) dominated thickets that have been subjected to a restoration method involving the planting of dense rows of P. afra truncheons for various time periods and also in degraded and intact thickets. I also planted nursery propagated P. afra cuttings. An average of 30 propagules of each species, were planted in each of the chosen areas in two distinct seasons that exhibited distinct rainfall peaks. Sixteen propagules of P. afra were also planted in each treatment only once. Propagules of the two thicket woody canopy species (S. longispina and P. capensis) showed a total survival of 1% and 9%, respectively. Survival of L. ferocissimum and R. obovatum was 19% and 70% and all propagules of P. afra survived. Analyses showed that survival is primarily tied to a species effect, with R. obovatum and P. afra showing significantly better survival than the other species. Within the other surviving few species a significant preference for overhanging canopy cover was observed. The results show little significance of restoration treatment for propagule survival, suggesting that a range of conditions is needed for the successful establishment of canopy species that likely involves a microclimate and suitable substrate created by canopy cover and litter fall, combined with an exceptional series of rainfall events. I found that the high costs involved with a biodiversity planting endeavour, and the low survival of propagules of thicket canopy plant species (P. afra excepted), renders the proposed biodiversity planting restoration protocol both ecologically and economically inefficient. Restoration success involves the autogenic regeneration of key species or functional groups within the degraded ecosystem. Heavily degraded spekboom-dominated thicket does not spontaneously regenerate its former canopy species composition and this state of affairs was interpreted in terms of a state-and-transition conceptual model. Floristic analyses of degraded, intact and a range of stands under restoration treatment for varying time periods at two locations in Sundays Spekboomveld revealed that the stands under restoration are progressively regenerating canopy species biodiversity with increasing restoration age, and that intact sites are still the most diverse. The high total carbon content (TCC) measured within the older restored stands Rhinosterhoek (241 t C ha-1 after 50 years at a depth of 50 cm) rivals that recorded for intact spekboom thickets, and the number of recruits found within older restored sites rivals intact sites sampled. 2 The changes recorded in the above- and belowground environments potentially identify P. afra as an ecosystem engineer within spekboom dominated thickets that facillitates the build-up of carbon above- and belowground and the accompanying changes in soil quality and the unique microclimate aboveground, which enables the hypothetical threshold of the degraded state to be transcended. This restoration methodology is accordingly considered efficient and autogenic canopy species return was found to be prominent after a period of 35-50 years of restoration treatment.
